It's a kilogram weight called the International Prototype of the Kilogram (IPK), made in 1889 from 90 percent platinum and 10 percent iridium, and kept in a special vault in the BIPM headquarters. “In the present system, you have to relate small masses to large masses by subdivision. The mass m in kilograms (kg) is equal to the mass m in pounds (lb) times 0.45359237: m (kg) = m (lb) × 0.45359237. All modern mass measurements are traceable back to it - from micrograms of pharmaceutical medicines to kilos of apples and pears and tonnes of steel or cement. 95. The International Committee for Weights and Measures (CIPM) approved a redefinition of the SI base units in November 2018 that defines the kilogram by defining the Planck constant to be exactly 6.626 070 15 × 10 −34 kg⋅m 2 ⋅s −1, effectively defining the kilogram in terms of the second and the metre. Even though the definition of the kilogram was changed in 2019, the actual size of the unit remained the same. ›› Common weight conversions.

Based on the data, the kilogram appears to weigh … But while the extra accuracy will be a boon to scientists, Robinson said that, for the average consumer buying flour or bananas, "there will be absolutely no change whatsoever". After 130 years of faithful service, the so-called “prototype kilogram” upon which nations base their weight measurements was just replaced by a new standard based on fundamental laws of physics. Converting from kilograms to pounds is a common task in the realms of math and engineering, but, luckily, it's an easy one. But Le Grand K and copies of it stored in other countries, including the United States, won’t be riding off into the sunset just yet.

Instead of being based upon a shiny hunk of metal stored in a vault in Sevres, France, on the outskirts of Paris, the kilogram is now based on the Planck constant, a tiny, unvarying number that plays a key role in quantum physics. “It’s going to be a while before people believe in electrical measurements,” he said, referencing the new definition of the kilogram.

The problem is, the "international prototype kilogram” doesn't always weigh the same. Even inside its three glass bell jars, it gets dusty and dirty, and is affected by the atmosphere. Since it’s based not on a physical object but on a mathematical constant, the new kilogram isn’t subject to such changes. Just as the metre - once the length of a bar of platinum-iridium, also kept in Paris - is now defined by the constant speed of light in a vacuum, so a kilogram will be defined by a tiny but immutable fundamental value called the "Planck constant".
